matt, 
Our solar kiln build is progressing nicely. We got most of the roof (except the ridge cap) installed at the weekend, and insulation in the south wall.
Already, even on a cloudy day in February in #vermont (peaked at 24,000 lx), we still saw a temperature differential of +14°F vs outside.
Just need a sunny day to see how it’ll really perform! Hoping to get more done this weekend.
